Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “However, in the reactive world, we use ReactiveCrudRepository or R2dbcRepository.”

A block of code is set as follows:

# Enable H2 Console
spring.h2.console.enabled=true
# Database Configuration for H2
spring.r2dbc.url=r2dbc:h2:mem:///testdb
spring.r2dbc.username=sa
spring.r2dbc.password=
# Schema Generation
spring.sql.init.mode=always
spring.sql.init.platform=h2

Any command-line input or output is written as follows:

./gradlew bootRun

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Once you’ve made all the selections, click on the Generate button to get the ready-to-build project.”
